Question

Find the measure of each interior angle of a regular octagon. (A regular polygon is one that has all the same sides and angles). [1]

Answer 1

The interior angle of a regular octagon is 135 degrees.

What is an octagon?

An octagon is a polygon that has 8 sides. Therefore, a regular octagon is a octagon with all it sides and angles equal to each other.

Therefore, the sum of angles in an octagon is each interior angle multiply by the number of sides.

Therefore,

n = number of sides = 8

Hence,

interior angle = (n - 2)180 / n

interior angle = (8 - 2)180 / 8

interior angle = 6 × 180 / 8

interior angle = 1080 / 8 = 135°
